Privacy
The short version: your pay details never leave your device. There's no account, no server-side database, and nobody at Hard Knock Life can see what you earn.

What we store, and where
Hard Knock Life runs entirely in your web browser. When you set up your clock, we save the following in your browser's IndexedDB storage, on your device only:
- Your nickname, if you give one
- Your pay rate or salary, hours, usual shift pattern and unsociable-hours rules
- Pension, student loan, tax region, tax code and other deduction settings
- Your travel methods and costs, and your break settings
- Your current shift, past shift totals and the log of items you've unlocked
None of this is uploaded, synced or shared. If you use Hard Knock Life on two devices, each keeps its own separate data unless you move it with an export file.
What we don't do
- No sign-up, email address or password
- No advertising or tracking cookies
- No selling or sharing of data, because we never receive it
- No third-party fonts or scripts loaded on the app pages. Fonts are served from our own domain.
Server logs
Like any website, the server hosting hardknocklife.co.uk may keep standard access logs (IP address, browser type, page requested, time) for security and to keep the site running. These logs never contain your pay or shift details, which stay in your browser.
Offline use
To work offline as an installed app, Hard Knock Life uses a service worker to cache its own pages, fonts, icons and the item price list on your device.
Your control
- Export: Settings → Your data → Export backup downloads everything as a JSON file.
- Import: restore that file on any device.
- Delete: Settings → Your data → Delete all my data wipes everything at once. Clearing your browser's site data for hardknocklife.co.uk, or uninstalling the app, does the same.
About the numbers
Take-home figures are estimates built from what you enter and the 2026/27 UK Income Tax, National Insurance and student loan rates published by HMRC and the Scottish Government. They aren't financial or tax advice. Your payslip is the real thing.
Item prices come from a list of typical UK consumer prices and are a rough guide only.
